Filed July 30, 1932 Patented May 23, 1933 UNITED STATES PATENT oF-FI-ca l. FREDERICK HLNLLH, OF BATTLE CREEK, MICHIGANQASSIGNOR T H. B. MANUFACTURING OOI PANY; OF BATTLE CREEK, MICHIGAN, A CORPORATION OF MICHIGAN Application filed my to,

This inventionis an improvement in lawn sprinklers or sprayheads of the type which are ordinarily connected in series by short lengths of hose. When such heads as heretofo're constructed are so connected and the hose coupled fast at either end and the water pressure is turned on there is a tendency for the hose to twist and tip the sprinkler heads up, or over. The hose is apt to be somewhat twisted when empty of water and water pressure tends to straighten it out and produce a c'onvulsively twisting motion in the hose and if the spray head is connected rigidly between the lengths of hose it is not heavy enough to overcome this twisting motion.

One object of the present invention is to prevent twisting of the hose connected to the spray head overturning or affecting the operative position of the spray head: Another object of the invention is to simplify and.

improve the construction of the spray head.

In the accompanying drawing I have illustrated a spray head embodying the invention, and will describe. the same with reference thereto, and summarize in the claims the novel features of the invention for which protection is desired.

In said drawing: s. Fig. 1 is a perspective view of one of the spray heads connected to hose sections.

Fig. 2 is a longitudinal vertical section through the spray head. Fig. 3 is a section on the line 3+3, Fig. 2.

The spray head shown comprises a tubular body portion 1 made out of drawn sheet metal and havingone end exteriorly threaded as at 1a. for the engagement of the female member '8 of an ordinary hose coupling attached to a hose section H. The other end of this bod is unthreaded and inturned. The body 1 is preferably made of drawn brass and is provided on its upper sidewith an integral hollow annular boss 16 which is pressed out of the metal of the body and is provided with a central aperture 10 for the escape of water. Within this boss is secured a perforated disk 3 which is provided with spaced openings 3a for the passage of water and which cause the water to be disseminated before it reaches the SPRAY 1 1932. Serial No. 627,394.

opening 10 and to issue as a spray through'the opening 10. I p In the lower side of the body is an approximately oval pressed out of the metal of the body and adapted to fit in and project through an opening in the transversely disposed base member 6, and its outer end is swaged to lock the body 1 securely to the base; see Figs. 1 and 3.

Connected with the unthreaded end of the body 1 is a female coupling member 4 whose outer end is internally threaded for engagement with the male member 8a of an ordinary hose connection attached to a hose section H", Figs. 1 and 2. The shank of the coupling member 4 is rotatably entered within the shaped hollow protuberance 1e unthreaded end of the bodyand is provided with an annular groove for the reception of a washer 5. Preferably this shank isprovided with an annular bead or bend 4?) at its inner end and with another annular bead or bend 4c spaced from the bend 4b, the exterior space between the beads 46, 40 forming an annular groove for the reception ofthe washer 5. The beads 46, 40 are slightly lessin exterior diameter than the internal diameter .of the body 1. The couplingv member 4 being rotatably connected to the body forms a swivel connection between the body and hose section H as indicated in Figs. 1 and'2; if there is any twisting or buckling of the hose-when the water pressure is turned on such swivel con nection between the hose and the sprinkler head permits the hose to twist but the spray head to remain inproper working position. In assembling the parts the washer 5 is placed in the channel between beads 46, 40 then the shank'of coupling member 4 is iny serted in the unthreaded end of the body 1,

the washer 5 fitting closely between the exterior of the shank and the interior of the body as shown inFigs2 and 3,'.then the outer extremity of the unthreaded end of the body is turned in against the outer side of the rib 40 as indicated at 1f and permanently connectsthe coupling member 4 to the body but permits it to turn therein.

The washer 5 is preferably a split washer,

as shown in Figs. 2 and 3 so that the water pressure will spread the washer and force it against the opposed walls of the body and shank and create a tight joint. Other suitable packing such as a soft spongy packing or a cup washer, which under water pressure willmake a tight joint, might be used. The construction is such that at the female end of the sprinkler head there is a swivel motion between the hose and head regardless of how tightly the coupling 8a is screwed in, with the result that the sprinkler head becomes self aligning and when the hose twists it does not raise or turn over the sprinkler head.

This same spray head may be used as a single sprinkler by detaching hose H therefrom and applying an end cap 7 as indicated in Fig. 3 and the twisting of hose H would not aifect or displace or overturn the sprinkler.

I claim I 1. A sprinkler head comprising a body having one end threaded for engagement with a member of an ordinary hose connection, a coupling member having a threaded outer end for engagement with a member of an ordinary hose'connection and a shank por tion entered into the unthreaded end of the body and rotatably confined thereto by the inturned end of the body engaging the outer side of the adjacent bead, and a washer on the shank forming a tight joint between the shank and the body.

2. A sprinkler head comprising body having one end threaded for engagement with amember of an ordinary hose connection, a coupling member having a threaded outer end for engagement with a member of an ordinary hose connection and a shank portion having spaced annular beads entered into the unthreaded end of the body and rotatably confined thereto by the inturned end of the body engaging the outer side of the adjacent bead, and a washer interposed between the beads and forming a tight joint between the shank and the body.

3. A sprinkler head comprising a cylindric body of drawn sheet metal having one end threaded for engagement with a member of: an ordinary hose coupling member and haw ing a lateral outwardly projecting boss'provided with an aperture for the escape of W3? ter, a drawn metal coupling member having its outer end threaded for engagement with a member of an ordinary hose coupling and having a shank portion entered into the unthreaded end of the body and confined. therein by the inturned end of the body, and a washer forming a tight joint between the shank and the body.

4. A sprinkler head comprising a cylindric body of drawn sheet metal having one end threaded for engagement with a member of an ordinary hose coupling membecand having a lateral outwardly projecting boss provided with an aperture for the escape of water, a drawn metal coupling member having its outer end threaded for engagement with a member of an ordinary hose coupling and having a shank portion formed with spaced annular beads entered into the unthreaded end of the body and confinedtherein by the inturned end of the body engaging the outer side of the adjacent bead, and a washer interposed between the beads forming a tight "joint between the shank and the body. I

5; A sprinkler head comprising a eylindric body portion made of drawn sheet metal having one end threaded for engagement with a member of an ordinary hose coupling and having a lateral outwardly projecting integral boss provided with an aperture for the escape of water, and an integral out wardly pressed lug opposite the boss for engagement with a base member a drawn metal coupling member having a threaded outer end for engagement witha member of an. ordinary hose coupling and having a shank port-ion provided with spaced annular beads and entered into the unthreaded end of the body and confined therein by the inturned end of the body engagingthe outer side of the adjacent bead, a washer between-the beads forming a tight joint between the shank and the body, and a transverse base member having an opening nto whi ch the lug on the body is entered, said lug being swaged, in said opening to fasten the body to the base.

6. A sprinkler head comprising a body hav ing an outlet orifice, means to prevent rota tion of the body; a coupling member having a threaded outer end for engagement with a member of an ordinary hose connection and a shank portion having beads entered into the unthreaded end of the body and rotatably confined thereto by the inturned end of the body cl'igaging the outer side of the adjacent bead, said shank having an annular washer receiving recess, and a washer in said recess forming a tight joint between the shank and the body. i
